4 Claims. (Cl. 149) A snap-on applying implement according to the invention can be quickly attached to a conventional carpenters hammer by inserting the hammer head in the socket member, snapping the handle in the open clamp, extending upwardly and turning the front end of the spring arm in, behind the hammer head while seated in the socket member, in which the spring arm forces it forward in place. The tool being attached is now in readiness for use.

To remove the hammer from the tool simply slide the spring arm from the back of the hammer head, press down on the handle, and the hammer is released from the socket.

The invention will be further described with reference to the attached drawings in which:

Figure l is a side view of a fastener attached to the snap-on implement in accordance with the invention when attached to a conventional hammer.

Figure 2, a top view partly in section taken on the line II, of Figure 1.

Figure 3, an end view of the implement connected to the hammer as shown in Figure 1, showing the structure of the spring arm when attached to the stapling arm 17, extending upwardly, then transversely, then downwardly to embrace the handle 11, as shown in Figure l, and Figure 3.

Figure 4 is to show the structural assembly in which 17 represents the stapling arm, whereas 25 represents the manner of pivotally connecting the spring arm 24, to the stapling arm 17, as shown in Figure 4, said pivotal connection being a large flat head screw 25, as required to hold the spring arm rigidly against the stapling arm.

In the drawings a conventional carpenters hammer is shown having a handle 11, a head 12, the driving portion of the head 12, has a neck part 13, and an enlarged driving head 14. A stapler 15, is shown attached to the hammer 10.

At the forward end of the staple driving arm 17, a socket 21 is attached and as shown in the drawnigs, is

nited States atent O "ice shaped to receive the driving head 14, of the hammer 10. Part of the edge 22, at its forward end of the socket 21, is turned in, to engage with the upper edge of the driving head 14, Figure 1, while half of the edge 23, of the socket is reduced in height, exposing an area of the driving head 14, of the hammer 10.

A spring arm 24, is connected pivotally to the stapling arm 17, by a screw 25, which is a bearing for spring movement.

The spring arm 24 extends past the screw 25, to form a support member 26, extending upwardly and is bent to fit over and embrace the handle of the hammer 11, as shown in Figure 3. The support member 26 is in part U-shaped so that the handle 11, of the hammer, can be sprung in to it.

What I claim as my invention is:

l. A snap-on attachment for a stapling machine having a stapling arm for attachment to a conventional hammer having a head, said attachment comprising a socket fixed at the forward end of the stapling arm and having means to receive the hammer head, a spring arm pivotally connected at the opposite end of the stapling arm and extending toward said socket to frictionally engage and bear against the hammer head in said socket and extending in the other direction upwardly and provided with means to clampingly engage the handle of the hammer.

2. A snap attachment as in claim 1, in which the pivotal connection is a bearing providing movement of said spring arm from and to said hammer head to rigidly lock said head to said stapling arm.

3. A snap-on attachment as in claim 1, in which at least a part of the edge of the socket is turned inwardly for engagement with a front edge of the hammer head, while the rear half of the socket next to the spring arm is reduced in height to freely receive the hammer head for ready engagement by the spring arm to clamp the attachment to the hammer.

4. A snap-on attachment as in claim 3, in which the spring arm extending upwardly is reversely formed to engage the hammer handle and its length upwardly is such as to hold the hammer handle when the hammer head is in the socket that the handle is substantially parallel to the staple driving arm.
